The present invention relates to the technical field of blow molding machine control, in particular to an electric mold opening and closing system based on an extrusion blow molding machine. The present invention is provided with a mold opening and closing assembly, an acquisition module and an analysis and control module. An analysis unit acquires data detected by a wall thickness detection unit, constructs thickness change curves of material thickness in different areas inside the mold opening and closing assembly, determines specific material curing areas based on the characteristic duration of each thickness change curve, calculates a material extension characterization value based on the characteristic parameters of the thickness change curves of the material thickness in each specific material curing area and parison characteristic information, and a control unit controls the operation parameters of the mold opening and closing assembly based on the material extension characterization value. In the preparation process of products with different extension requirements for each area of the parison, the system realizes the targeted characterization of the characteristics of the specific preparation areas, and adaptively adjusts the operation parameters of mold opening and closing based on the characteristic parameters of the specific areas, thereby improving the blow molding quality of plastic products.
